• Description:
  Advanced composite materials such as fiberglass and graphite do not have corrosion problems like steel. Hence, they are studied in this project for their feasibility to use in prestressed concrete bridge decks. The mechanical properties of these cables were tested and compared with steel cables. A combination test was developed to evaluate the quality of prestressing cables. The fiberglass and graphite cables successfully completed this test. The concrete environment with sodium chloride on the cables was tested, and the short-term study did not product any damage to fiberglass cables. The pull-out strength and slip critical beam tests did not show any damage to bond between cables and concrete. The transfer length and development length of fiberglass and graphite cables were determined, and they were comparable with steel cables.
